My goal is the following: * split the network flows into different priorities. ssh & telnet traffic most high, web traffic priority 2nd high, etc… BT traffic most low. * put as much higher priority traffic as possible (up to 100Mbps) to provider 1 and the rest of the traffic to provider 2 * If provider 1 get unavailable, switch all the traffic to provider 2. When provider 1 gets back online, switch the traffic back. I don’t have a clue how to set this up.

I don't know any open standard protocols can satisfy your needs. To the best of my knowledge, you can use OSPF to do equal load sharing between two routers, but obviously this is not what you want to do. Many of the enterprise firewalls/routers does have the spill-over wan load balancing feature (dell sonicwall/watchguard) which should be able to do what you want to do. -- To unsubscribe from this list: send the line "unsubscribe lartc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
